Regression: fix mounting NFS when NFSv3 support is not compiled
Trying to mount NFS (root partition in my case) fails if CONFIG_NFS_V3
is not selected. nfs_validate_mount_data() returns EPROTONOSUPPORT,
because of this check:
#ifndef CONFIG_NFS_V3
if (args->version == 3)
goto out_v3_not_compiled;
#endif /* !CONFIG_NFS_V3 */
and args->version was always initialized to 3.
It was working in 2.6.36
